FOLDING CAM P-STOVE.

SPECIFICATION forming part of Letters Patent No. 585,046, dated June 22,1897.

Application filed May 18, 1896. Serial No. 591,404. (No model.)

To all whom it may concern:

Be it known that I, CHARLES S. PENFIELD, a citizen of the United States,residing at S pokane, in the county of Spokane and State of Washington,have invented new and useful Improvements in Folding Camp-Stoves, ofwhich the following is a specification.

My invention relates to folding campstoves, and has for its object toprovide a culinary apparatus that will be light, cheap, durable, andcapable of being packed in a small space for transportation as part of acamp outfit and which can be quickly unpacked and easily set up for use.

The invention consists in the features of construction and novelcombination of parts comprised in a folding camp-stove and onlinaryoutfit, as hereinafter more particularly described and claimed.

In the annexed drawings, illustrating the invention, Figure 1 is alongitudinally-sectional elevation of my improved folding campstove withfolding oven supported on the stove-top and a folding bake-pan inclosedin the oven and resting on a folding support. Fig. 2 is a frontelevation of the stove or firebox and lower portion of the oven. Fig. 3is a perspective of the oven inverted and "partly folded. Fig. 4 is asection through a portion of the top and one side of the folding oven.Fig. 5 is a view of the bake-pan folded. Fig. 6 is a section through aportion of the bottom and one side of the folding bake-pan. Fig. 7 is aview of the bake-pan support partly folded. Fig. 8 is a view of thestove or firebox inverted and partly folded. Fig. 9 is an under view ofone corner of the fire-box. Fig. 10 is a longitudinal section oftelescopic stovepipe with flanged cups or vessels inserted in the endsof the nested pipe-sections.

Referring to Figs. 1, 2, and 8, the referencenumber 11 designates thetop of the firebox or stove proper, which top is constructed ofsufficiently heavy sheet metal and provided with a depending flange 12on all sides. The edge of this flange is provided with a bead 13 andinserted wire 14 for strength and stiflness.

Within the flange 12 and close to the under side of the fire-box top 11are hinged a stoveback 15 and a stove-front 16, each consisting of arectangular piece of sheet metal, the stove-back being hinged at 17,Fig. 1, and the stove-front being hinged at 18, Figs. 1 and 8. Byhinging the stove-back 15 and stove-front 16 in the angles formed by thestove-top 11 and end flanges 12, as shown, said back and front will becapable of folding closely against the under side of the top in makingthe stove ready for transportation. It is preferable to provide the sideedges of the back 15 and front 16 with narrow flanges 19, Fig. 1, andtheir lower edges may be folded over or beaded at 20, as shown, toprevent breaking and impart a requisite stiffness.

In the stove-front 16 is arectangular opening closed by a fuel-door 21,hung on hinges 22, Fig. 2, and provided with a pivoted latch 23, havinga looped end working in a guardstrap 24 and adapted to engage a catch 25on the outside of the stove-front.

The sheet-metal stove sides 26 are hinged to lugs 27, Figs. 1 and 8,that are riveted to the inner sides of the side flanges 12, depend ingfrom the stove-top. These hinged stove sides 26 are each provided ontheir side edges with flanges 28, Figs. 2 and 8, that help to supportthe stove back and front and close the joints of the fire-box whenunfolded or opened out for use, besides assisting to stiffen or bracethe sides. The stove sides 26 are also stiffened or braced by havingtheir lower edges 29 turned over or beaded, as shown.

By reference to Fig. 8 it will be seen that in packing the stove fortransportation the back 15 and front 16 are first folded against theunder side of the top 11 and then the sides 26 are folded successivelyinward upon the hinged front and back pieces. One of the sides 26 may beslightly shorter than the other to facilitate compact folding of theparts together.

In unfolding the stove or fire-box the sides 26 are first turned outwardto a vertical position and then the back and front pieces, respectively,thus forming a rectangular sheetmetal box.

The lower corners of the side pieces 26 are provided with perforations30, Fig. 8, for the passage of tie-rods 31, having hooked ends 32 andprovided with thumb-nuts 33 on their other ends which are suitablescrew-threaded. By this means the lire-box when set up, as shown inFigs. 1 and 2, will be securely braced and prevented from spreading orcollapsing with any weight placed thereon.

It will be observed that the fire-box is entirely open at the bottom, itbeing intended that the fire shall be built upon the ground. The door 21is for use in supplying fuel as required, and a portion of the earth maybe scraped away beneath the stove-front to afford such draft as may beneeded.

The rear portion of the stove-top 11 is provided with a smoke-hole 34,Fig. 1, flanged 'on the outside for attachment of a telescopicsmoke-pipe 35, formed in sections adapted to be nested one withinanother, as shown in Fig. 10, when not in use.

Among the appliances that may accompany the camp culinary outfit aremetal cups or vessels 36, having their bottoms provided with broadflanges 37, so that when these vessels are inserted into the ends of thenested stovepipe-sections, as shown in Fig. 10, the flanges 37 willextend across and protect the ends of the pipe-sections from access ofdirt and moisture.

There is provided for use on the stove-top a collapsible or foldingoven, Fig. 3, constructed of sheet metal. This oven comprises a top38,'having two opposite sides turned down to form a flange 39, Figs. 3and 1. The ends of the oven-top piece 38 are not flanged, but have theend pieces 40 attached thereto directly by means of hinges 41, as shownin Fig. 3, so that these ends 40 will fold closely against the underside of the oven-top.

The oven sides -12 are hinged on their inner sides at 43, Figs. 3 and 1,to the edges of the flanges 39 on the sides of the oven-top, and it willbe observed by reference to Fig. 4 that the oven sides 42 and theirhinges 43 are so arranged that a portion of each oven side is extendedalong the outside of the flange 39 when the oven is unfolded, thusproviding a secure bracing therefor. The side edges of the oven sides 42are provided with flanges 44, that assist in supporting the oven endpieces 40 when the oven is unfolded and placed in position.

At their lower edges the oven end pieces 40 and side pieces 12 may beturned over or provided with beads or flanges 4C5,that will impart thenecessarystiffness. The side edges of the end pieces 40 may be alsoprovided with flanges -lti,which,as shown in Fig. 1,1naybe folded overat their ends and slightly sprung at the center to give additionalstiffness. A handle 47, Fig. 1, is provided on the oven-top forconvenience in removing the oven to give access to its contents, theoven being wholly open at the bottom, as shown in Fig. 1. By referenceto Fig. 3 the manner of folding the oven into a flat compact body willbe readily apparent.

For use with the oven there is provided a folding sheet-metal bake-pan,Figs. 2 and 5,

which comprises a bottom. 4C8, closely-folding end pieces 49, and hingedside pieces 50, provided with flanges 51 on their side edges. The endpieces i9 are hinged directly to the ends of the pan-bottom 4S, and thesides 50 are attached by hinges 52 to flanges 53 on the sides of thepan-bottom, the construction be ing substantially the same as thatalready described with reference to the oven.

In order to support the bake-pan away from direct contact with the topof the stove or fire-box, there is provided a removable openwork supportor pan-holder 54, consisting of a sheet-metal grid or frame havingflanged or beaded edges and provided with inwardlyfolding feet 55, eachpair of feet being formed from a single piece of wire bent to the formshown in Fig. 7 and connected by hinges 5G to the body portion of theholder. This makes a very convenient, light, but strong pan-support thatcan be easily folded into a flat form.

It will be apparent that the fire-box or stove and its accompanyingappliances can be quickly and easily folded or packed into close compactform for transportation with a camp outfit. The several parts are lightand easily handled and will withstand hard usage without liability ofbreaking.

It is a peculiar advantage of the stove construction herein shown anddescribed that it is especially designed with reference to easy andconvenient packing on a horse, the entire stove outfit being so small inbulk that it will occupy but little space in a pack, and yet when set upfor use the stove is capable of fulfilling the requirements of heatingand cooking for a small party of men.

The usual camp-stoves heretofore on the market have pot holes and lidswhich are elements of weakness and bulkiness, and they are mostly ofcomplicated construction and not readily brought within a small compass.

The strength, durability, small bulk, and convenience in packing, whichare features of my stove, make it particularly useful for meeting thewants of hunters, prospectors, surveyors, and campers generally.

lVhat I claim as my invention is 1. In a folding camp-stove, thecombination of the stove-top having a depending flange around all itssides, the stove-back and the stove-front hinged in angles between saidtop and the end flanges of the top, the said front being provided With alaterally-swinging door and its fastenings, the stove sides hinged tothe edges of the side flanges on the stove-top and having their lowercorners provided with perforations, and the detachable tie rods adaptedto engage in said perforations and brace the unfolded stove sides,substantially as described.

2. In a folding cam p-stove, the combination with the fire-box, of afolding oven consisting of a top provided with depending side flanges,end pieces hinged directly to the end edges of said top, and side piecesprovided with inwardly-flanged ends and. hinged to the edges of the sideflanges on the oven-top and extended outside said side flanges, wherebythe .said side'flanges of the top Will brace the unfolded oven sides,substantially as described.

3. In a camp-stove, the combination with a telescopic smoke-pipecomposed of sections adapted to nest one Within another of the'ves seisadapted to close the ends of the nested 1 o pipe-sections and providedwith broad flanges to extend across the ends of the outer pipesection,substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
